DANIEL LEWIS AND KATHARINE LEWIS, OF BUFFALO, NEW YORK. l:

COOKING-PAN.

Specication of Letters Patent.

Patented July 30, 1907.

Application filed March 28, 1907- Serial No. 364,996.

To all whom it may concern.'

Be it known that we, DANIEL LEWIS and KATHARINE LEWIS, citizens of theUnited States, residing at Buffalo, in the county of rie and State ofNew York, have invented certain new and useful Improvements inCooking-Pans; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecification.

Our invention relates to improvements in cookingpans for roasting orbaking and more particularly to that type which involves a pan andcover, the bottom of the pan being held away from contact with theheat-4 ing surface upon which such pan rests.

The objects of our invention are to simplify the construction, increasethe durability and cheapen the cost of production of the pan.

To these ends our invention consists of a pan struck up from one pieceof sheet-metal, having a rounded vertical side-wall with a lower off-setportion, a bowlshaped bottom and a s'upporting-ange for holding thebowl-shaped bottom away from contact with the heating surface upon whichthe pan rests, such supportingflange extending below the bottom andbeing formed by doubling over upon itself, into the off-set portion, theside-wall of the pan, below its line of junction with the bowl-shapedbottom.

Our invention further consists of certain details of construction, allof which 'will be fully hereinafter described and claimed.

In the drawings, Figure 1 is a central vertical section of our improvedpan. Fig. 2 is a similar section of the cover.

Referring to the drawings, l is the rounded vertical side-wall of ourimproved pan, preferably cylindrical in configuration, to save waste incutting from the blank,

but such side-wall may be oval or elliptical, if pre-` ferred. Its upperedge is bent out at right-angles to form the horizontal shelf 2, uponwhich the cover rests, its extreme outer edge being curled tol form thestrengthening bead 3, on the under side of the supporting shelf 2.

The lower portion ofthe side-wall 2 is preferably offset, as at 4. Thesupporting-ange' is formed by doubling over upon itself, into theoff-set portion, the sidewall l of the pan, the lower edge of thedoubled portion forming the supporting-flange, being preferably bentoutwardly to form the flaring portion 6, which serves to increase therigidity of the supporting-flange.

The bottom 7 of the pan is preferably bowl-shaped, its line of junctionwith the side-wall 1 of the pan being at the upper edge of the off-setportion and extending into the same, to form a tight joint. The bottom 7of the pan is raised a short distance from the plane of the lower edgeof the supporting-flange, in order that such bottom may be held awayfrom contact with the heating surface upon .which such pan rests, inorder that the burning of the contents of the pan may ybe prevented.

As clearly shown, all of the parts of our improved pan, just described,are formed from a single piece of sheetmetal, thus producing a one-piecepan, possessing increased rigidity and stability. The cover is alsoformed from one piece of sheet-metal comprising a rounded top 8, roundedvertical side-wall 9, an outwardly extended horizontal iiange 10, formedby bending over upon itself, a portion of the side-wall of the cover andan outside bead Il, formed by curling over thelower edge of the cover.This bead l1 is adapted for snug frictional contact with the innersurface of the sidewall l of the pan and the horizontal flange l0 restsupon the horizontal shelf 2 of the pan and supports such cover inposition upon the pan. The cover is provided with the usual handle 12. l

The construction of the cover, just outlined, possesses no patentablenovelty, our invention residing entirely in the peculiar construction ofthe pan, hereinbefore specifically described. v

It will be observed that our improved pan has no crevices or spaces,either inside or outside, in which grease or dirt can lodge, thus makingit a perfectly sanitary cooking pan.

We claim.

1. A cooking pan struck up from one piece of sheetmetal, having arounded vertical side-wall with a lower offset portion, a bowl-shapedbottom and a supporting-flange for holding the bowl-shaped bottom awayfrom contact with .the heating surface upon which the pan rests, suchsupporting-flange extending below the bottom and being formed bydoubling over upon itself, into the olf-set portion, the side-wall ofthe pan, below its line of junction with the bowl-shaped bottom.

2. A cooking pan struck up from one piece of sheetmetal, having arounded vertical side-wall with a lower offset portion, a bowl-shapedbottom and a supporting-flange with outwardly flaring lower edge forholding the bowlshaped bottom away from contact with the heating surfaceupon which the pan rests, such supporting-ange extending below thebottom and being formed by doubling over upon itself, into the off-setportion, the side-wall of the pan, below its line of junction with thebowl-shaped bottom.

In testimony whereof, we have signed our names to this specification, inthe presence of two subscribing witnesses.
